This invention relates to shelf edging and, while adapted for general application, is particularly useful in connection with shelf edgings made in whole or in part of paper. 1

The object of the invention is to provide a shelf `edging of `novel and pleasing appearance which may be economically manufactured and will hold its shape 'well when placed on a shelf. The edging of this invention has a bound or nished upper edge, formed by folding a projecting marginal extension of one facial ply over the upper edges of a plurality of other plies and securing it in face-abutting relation with the other facial ply, preferably by an adhesive. The folded over marginal extension of the one facial ply may be substantially flush with the exposed face of the latter ply or otherwise, and the plies may be embossed or provided with perforated and printed ornamentation, or both, to produce highly ornamental and pleasing designs.

It is of importance in the present invention that, when the plies are assembled, one of the facial plies is offset to provide a recess into which the marginal extension of the other facial ply is received. This offset has a pronounced strengthening effect upon the upper margin of the edging and tends to hold the upper edge straight against the front edge of a shelf and preclude buckling. I am thus able, by the present invention, to produce a highly efficient shelf edging with marked economies, while the resulting structure possesses the mechanical requirements for a nice tailored nt when placed on the shelf.

The structure is such, moreover, as to permit of an almost unlimited choice of designs without appreciably increasing the cost of manufacture.

Features of the invention, other than those adverted to, will be apparent from the hereinafter detailed description and claims, when read in conjunction with the accompanying drawing.

The accompanying drawing illustrates different practical embodiments of the invention, but the constructions therein shown are to be understood as illustrative, only, and not as defining the limits of the invention.

Figure l is a front elevation of a three ply edging embodying the present invention.

Figure 2 is a section perspective taken on the line Z--2 of Figure l.

Figure 3 shows short lengths of the several plies and illustrating the manner in which they i are formed prior to assembling.

(Cl. lidw-10) Figure e is a View similar to Figure 2, showing a modified form of the invention.

Figure 5 shows a further modified form of the invention.

While the edging of this invention may embody three or more plies of material, I have chosen three plies as thoroughly satisfactory in the production of an economical and thoroughly efcient structure. In the showing of Figures 1 3, l designates the back ply, 2 the intermediate ply and 3 the front ply. The back ply is adapted to be folded over the 'upper edges of the other two plies along a fold line indicated at 4. As shown in Figure 3, the body oi the back ply l projects downwardly from the fold line l for the desired overall width or the edging and it is provided at its top with a marginal extension 5 which projects a sufficient distance above the fold line to provide an adequate flap for folding over the upper edges of the other plies. The free edge of this extension may be made straight or may be of any suitable configuration. For the purpose of illustration, it is shown as serrated at E.

The intermediate piy is adapted to be secured in face abutting relation to the back ply. It is shown as extending downwardly to the lower edge of the back ply, although it may extend for a greater or lesser distance in this direction. It, however, terminates at its upper edge short of the 30 fold line t. `a distance about the same as the distance which the extension 5 projects beyond the fold line d, so that, when the plies i and 2 are adhesively secured together in face abutting relation, as indicated by the adhesive 'I in Figure 2, the extension 5 will project beyond the ply 2 a distance about twice the distance of the upper edge 3 of the intermediate ply 2 from such fold line. The front ply 3 is of a width to extend from the fold line downwardly to an elevation preferably short of the lower edges of the other plies l and 2, as clearly shown in Figure 3.

In the structure thus far described, the several plies are assembled at the elevation shown in Figure 3. The ply 2 is iirst laid on the ply l at 45 the relative elevation shown, and the ply 3 is then laid on the ply 2. The plies l and 2 are racially secured together by gluing them throughout or `at spaced apart points, and the ply 3 may be similarly secured in place. However, I preferably leave the ply Ii` loose below the upper edge 8 of the intermediate ply, while the upper margin of the ply 3 is glued to the body of the back ply l below thefold line thereof. In some cases the front ply 3 is secured along its upper but portion to the front face of the intermediate ply 2. After the parts have been secured together, as stated, the extension of the back ply is folded over the upper edge of the front ply and secured in face abutting relation to the front ply. As this operation is carried out pressure may, if desired, be applied to the extension to flatten the extension 5 into flush relation with the front face IG of the front ply, although this pressure may be dispensed with so as to leave a rolled or round upper edge, as shown in Figure 4, hereinafter described. The edges of the several plies may be scalloped, serrated or otherwise configurated as may be desired to carry out a predetermined design and one or more of these plies may be printed or perforated or both. As shown in Figures 1 3 of the drawing the front ply 3 is both perforated and printed. The perforations are indicated at II and form part of the predetermined design.

If desired, I may apply relatively great pressure to the parts as they are assembled, for the purpose of embossing said parts while gluing them together. In this way I am able to force the extension 5 to offset the front ply to give the fiush relation described and produce the offset I2 which serves in effect as a strengthening rib. At the same time the intermediate ply may be compressed to an extent as to cause said intermediate ply to be slightly bulged or embossed as indicated at I3 by virtue of the presence of the opening of the perforations I I. This is accomplished by pressing the front ply into the intermediate ply so as to form, in effect, a depression therein bordered at its lower edge by a shoulder I 4 at the lower edge of the front ply. At the same time an embossed lower edge I5 may be formed in both the intermediate and back plies 2 and I. When the parts are secured together in this Way a relatively thin edging is produced but one of marked strength and appreciable 1ongitudinal stiffness, due to the reinforcing of the upper edge by the folded over extension 5 and by the presence of the offset I2. Also, when the three ply structure at the upper margin of the edging is glued together as stated, an unusually stiff edge is provided which will hug the shelf closely and allow the edging to hang with a smooth tailored appearance. I wish it understood, however, that this pressure embossing is optional and that I may make the edging Without it if desired.

The structure shown in Figure 4 embodies a modification of the invention as hereinbefore described. Here the offset portion I6 of the front facial ply I 'I is made to terminate in distance short of the fold line 4, so that, when the rnarginal extension I8 of the back ply I9 is folded over, a part of this extension will come into face abutting relation with the back ply, While the rest of the extension will come into face abutting relation with the upper margin of the front ply I1. This arrangement produces two offsets or beads 20 and 2I which impart a double reinforce to the upper portion of the edging. The intermediate ply 22 terminates at the offset 2|, as in the preceding gures.

Figure 4 shows the structure as made without the application of appreciable pressures and with the parts glued together to hold them in assembled relation with the upper edge of the edging in the form of a relatively loose rolled or round edge and with the parts glued together as indicated by the solid black lines 23 in this flgure. It will of course be understood that the structure of Figures 1-3 may have the same kind of a round fold at the fold line.

It will be noted that when the intermediate ply is cut low and in spaced relation to the fold line, this results in economies in stock from which this ply is made. Also, this narrowing of the intermediate ply in Figures 1-4 or of both the intermediate and front ply as in Figure 4, serves to produce the offsets or strengthening beads to impart rigidity in the upper margin of the edging to hold the edging in close-fitting relation to the front edge of the shelf.

In the forms of the invention which I have chosen to show, the marginal extension is shown as formed on the back ply and is folded over the upper edge of the front ply to be secured to the front face of the latter. This arrangement, however, may be reversed so that the front ply will have the extension folded over and secured to the back face of the back ply. Such a reversed arrangement is shown in Figure 5 wherein the front ply is indicated at 24 and is provided with an extension 25 folded over the upper edge of the back ply 26, while an intermediate ply 21 terminates at its upper edge short of the free edge of the extension 25. For these reasons and others which Will be apparent from the foregoing description, the present invention is not restricted to the detailed showings of the drawing.
